I wouldn't touch the gears. With a 2.73 rear you have about the same contact area as a 4.10 Ford 9" rear. Go with a good sized stall with high STR to take advantage of the 2.73 rear gears. On LS1.com in the group purchases section check out the post about a GP on the MidWest torque converters. I used a 3200 2.5 STR MidWest converter in my 99 Z28 A4 3.23 car. I went from 13.1s @ 107mph to 12.2s @ 111mph from the converter on stock tires. I would go with a 3500-3600 with 3.0 STR and your car will fly. I drove mine 104 miles for work every day and the stall was not an issue.

P.S. I forgot to mention the price is around $450 for the converter. Cheaper than gears, install and a speedo calibration device.
